If you're using a Google Voice phone number to receive text messages, try temporarily using a different number that isn't attached to your Google Voice account.

If you are still not receiving text messages from SubAssistant, please check with your carrier to ask if they are blocking messages from "premium short codes".

As mobile networks have improved, we've all grown accustomed to messages arriving within a few minutes or even seconds; however, SMS (text messaging) isn't built as an instant messaging service, and as such, carriers don't guarantee a speedy delivery. Once a text or email leaves our servers, we are unable to track it or guarantee its delivery. It is normal, from time to time, to not receive a text message. SMS is a "best effort" protocol and as such cell carriers don't guarantee the delivery of SMS messages.
